Chinese Model Maps Lunar Water Ice Stability for Chang'e-7 Mission
Chinese scientists have developed a high-resolution model to evaluate the thermal stability of water ice in the Shackleton Crater region near the lunar south pole. This innovative tool is designed to guide the upcoming Chang'e-7 mission, scheduled for launch in 2026, as it seeks to locate and analyze vital lunar water ice resources.
This model is intended to provide guidance for the Chang'e-7 mission, which is scheduled for launch in 2026 and aims to locate and analyze lunar water ice.
Model Development and Methodology
The lunar polar water-ice thermal stability model was developed by a research team at the Key Laboratory of Solar Activity and Space Weather within the National Space Science Center (NSSC) of the Chinese Academy of Sciences. This sophisticated model integrates the thermal characteristics of lunar soil at extremely low temperatures. Its purpose is to simulate the distribution of surface radiation, soil temperature, and crucially, the specific areas where water ice can remain thermally stable.
The findings of this research were recently published in the Planetary Science Journal.
Relevance to Chang'e-7 Mission
The Shackleton Crater area is identified as a prospective landing site for China's Chang'e-7 mission. A primary scientific objective of this lunar probe is to conduct high-precision remote sensing and in-situ detection of water ice at the lunar south pole. The assessment provided by this thermal stability model is considered crucial for understanding the distribution of water ice in these extreme lunar polar regions, thereby directly guiding the mission's detection efforts.
The assessment of water ice thermal stability is considered crucial for understanding its distribution in lunar polar regions and for directing the mission's detection efforts.
Model Capabilities and Future Implications
Researchers affirm that the new model delivers a more detailed and precise map of potential ice deposits. It can calculate the distribution of illumination, lunar soil temperature, and stable regions for volatiles such as water ice. This capability is expected to significantly assist in identifying precise distribution areas for water ice, offering critical support for future detection missions, especially within the Chang'e-7 mission's designated landing zone.

Tang Yuhua, deputy chief designer of the Chang'e-7 mission, emphasized the broader impact of successfully locating lunar water ice. Such a discovery could substantially reduce the cost and time involved in transporting water from Earth. This development could facilitate the establishment of a human base for long-term lunar activities and support further exploration of Mars or deep space.
